APPARATUS FR MIXING LIQUIDS WITH GASES.

To all whom it may concern:

Be it known that 1, GUs'rAv DnTLnFsnN, a citizen ot' the United States, residing at Jersey City, Hudson county, State of New Jersey, have invented new and use'l'ul improvements in Apparatus for Mixing Liquids with Gases, of which the following is a specification.

lhis invention relates to an improved apparatus for mixing liquids with gases, the device being more particularly designed tor charging beer with carbonio acid gas while the beer flows from the chip cask to the racking apparatus. rlhe construction is such that the liquid is thoroughly agitated while being charged with the gas, so that an intimate admiXture is obtained.

in the accompanying drawing: Figure 1 is a side elevation of my improved apparatus, showing it coupled to a beer pump; Fig. 2 is a longitudinal section through the apparatus; ldig. 3 a detail of the lining et a left hand end view of Fig. 2, and Fig. 5 a right hand end view thereof.

A tubular casing is adapted to be oonnected at one end by coupling 11 to a beer pump 12, and at its other` end by coupling 13 to a hose 1/1 leading to the racking apparatus. l'vithin casing 10 are contained a series of battle plates that extend partly across the same and are adapted to vigorously agitate the beer while the latter is driven through `the casing by pump 12. rl`he carbonio acid gas is conveyed into casing 10 through a pipe 15 communicating with the casingl intermediate the battle platos, so that the intermixture between liquid and gas takes place while the `l'ormer is in its agitated condition. As shown, there depend from the roelI of casing' 10, a pair oi' battle plates 16, 19, arranged at opposite sides of gas pipe 15. Plates 16, 19, flank a pair of upwardly extending battle plates 17, 18, of which plate 17 is made in the form of a thick block located opposite pipe 15, while plate 18 is arranged sidewise of such pipe. lhe baille plates are of segmental shape and their relative size is such, that while the tree edge of plate 16 extends below the free edge of plate 17, a clearance is formed between the free edges oi' plates 18 and 19. Further, plates 16, 17 are placed into close proximity, plates 17, 18 are spaced a comparatively,

greater distance, and plates 18, 19 are again placed into close proximity. 1t' desired the ba'liie plates may be fitted into casing 10 by means oi' a tubular lining 20 which is encompassed by the casing and is slotted as at 21, 22, 23, 241, l'or the reception of plates 16, 17, 18, 19, respectively. By this construction the assemblage of the parts is facilitated and the plates are securely anchored to the casing. However, the entire device may be made in a single casting.

In use, the liquid is forced by pump 12 through the comparatively small opening beneath plate 16, and up along the contracted duct intermediate plates 16, 17 to be thrown as a subdivided -iet toward the gas that enters, by pipe 15, the mixing chamber 26 formed between plates 16, 19. By placing the comparatively thick batlie plate 17 opposite the entrance of the carbonio acid pipe 15, the agitated liquid is held in close proximity to pipe 15 for a length of time sutlicient for causing a thorough absorption of the carbonio acid by the liquid. lhe peculiar arrangement of the baffle plates provides a large mixing chamber between plates 16, 19, in which plate 18 serves to break up the stream flowing over plate 17, and to whirl it toward the narrow discharge passage 27, so that a thorough saturation of the liquid with the gas is obtained.

l claim:

1. device of the character describe l, comprising a tubular casing having a liquid inlet at one end thereof, a series of opposed battle plates within the casing, of which one plate is thicker than the other plates, and a gas inlet opposite said thicker plate, substantially as speci'lied.

2. A device of the character described, comprising a casing having a liquid inlet,a slotted lining inclosed by the casing, batlie plates engaging the lining-slots, and a gas inlet intermediate said plates, substantially as specified.
